NAME

     VFS_SET -- set up loadable file system vfsconf


SYNOPSIS

     #include <sys/param.h>
     #include <sys/kernel.h>
     #include <sys/module.h>
     #include <sys/mount.h>

     void
     VFS_SET(struct vfsops *vfsops, fsname, int flags);


DESCRIPTION

     VFS_SET() creates a vfsconf structure for the loadable module with the
     given vfsops, fsname and flags, and declares it by calling
     DECLARE_MODULE(9) using vfs_modevent() as the event handler.

     Possible values for the flags argument are:

     VFCF_STATIC     File system should be statically available in the kernel.

     VFCF_NETWORK    Network exportable file system.

     VFCF_READONLY   Does not support write operations.

     VFCF_SYNTHETIC  Pseudo file system, data does not represent on-disk
                     files.

     VFCF_LOOPBACK   Loopback file system layer.

     VFCF_UNICODE    File names are stored as Unicode.

     /*
      * fill in the ones we use, and use the vfs_std for the rest.

             myfs_mount,
